INSUIiATING AND PLASTER-HOLDING WALL AND CEILING COVERING.

' Original No. 1,598,881,. dated September 7, 1926, Serial No. reissue filed June 17, 1927.

This invention relates to improvements in A composition coverings designed for use particularly in forming interior and exterior walls, ceilings and partitions of building structures. i

The object of the invention is to provide such coverings formed of felt or heavy paper that will act as non-conductors of heat and cold, and as sound .deadeners; that are water proof, and are provided with a surface to which plaster-may be directly applied, and to which it will rigidly adhere, thereby permitting walls, ceilings and partitions of buildings to beconstructed without the use of the usual wood or metal lath and, if preferred, without the use of intermediate studding orposts.

The invention consists generally in' the constructions and combinations hereinafter described and the claims.

In the drawings,

Figure 1 is a perpective View of a portion of an interior wall formed of our improved covering without any intermediate studding, and with plaster applied directly to the surface of said covering, a portion of the plaster 7 being broken away to permit illustration of aportion of the surface of the covering;

' of the sheets by a Figure 2 is a detail sectional plan of aportion of the wall shown in Figure 1 with the plaster omitted to illustrate how the overlapping edges of the coveringmay be secured together;

Figure 3 is a perspective view showing the covering nailed to vertical studding with vthe plaster applied to one surface of the sheets only;

Figure 4 is a detail sectional plan of the structure shown in Figure 3 illustrating the manner of securing the overlapping edges single row of nails; F1gure-5 is a detail of the structure shown in Figure 3 with the asphalt layer applied to lone surface of the composition covering on y; I

Figure 6 is a view illustrating how. the sheets maybe constructed with .one edge adapted for an overlapping joint and the opposite edge for a butt joint;

Figure 7 is a. detail showing a single sheet with the asphalt layer applied to' each sur face thereof, W

Figure 8 is a detail sectional view showing a what is known particularly pointed out in 92,541, filed March 5, 1926. Application for Serial No. 199,613.

how two .sheets may be secured together when not provided with the longitudinal flanges shown in Figure 6; and

Figure 9 is a View similar to Figure 8 showing one of the sheets having a butt joint edge and the other a flanged edge.

In the drawings 22 represent sheets of i as dry or unsaturated felt, which is preferably composed of a mixture or vegetable and wool fiber, made by grinding up paper, rags and similar material. 'lhis material is preferably made in long sheets which are wound into rolls as the sheets are produced by the felting machine. The material is'cellular in construc tion and forms excellent insulation, against heat and cold andis also a non-conductor of sound.

lVe preferably employ two sheets of like material and secure the same together by placing between them a layer of' liquid asphalt 4 which not only binds the sheets together but forms a water proof coating between them. To the outer surface of one or both of the felt sheets, we also applya coating of liquid asphalt 5. In Figure 2 we have shown the asphalt applied to both of the outer surfaces of preferably be employed when the sheets are to be used for forming a partition or wall without intermediate studding, and to be plastered on both sides, as indicated in Figure 1 of the drawing.

Where the sheets are to be secured to spaced the composite sheet. This arrangement will studding 6, as shown in Figures 3 and 4,

the asphalt need be face as indicated in In forming the composite sheets we prefapplied to ,only one sur- Figure 5.

I erably arrange each sheet so as to project at ltS edge a short distance beyond the edge of the contiguous sheet, thereby making a projecting flange 7 at each edge of each sheet (see Figs. 3 and 4:). When the sheets are to be used without-spaced studding, as shown in. Figure 1 of the drawing, the edges 7 of the sheets are overlapped, as shown in Figure 2, and are secured together by staples 8, or by suitable nails or cement. When the sheets are to be secured to spaced studding,

as indicated in Figure 3, the overlapped edges of the sheets'may be nailed tothe studding, a single row of nails being used and driven through the overlapped edges of the sheets as shown in Figure 4.

' each edge,

If preferred, the sheets may be overlapped, as described, so as as indicated in if preferred the sheets may be severed lengthwise as indicated in Figure 6', thereby forming two sheets, each having one edge adapted for a butt joint and its opposite edge provided with the flanged edge already described. For forming inside walls and partitions, we may use a single sheet of felt and apply the liquid asphalt thereto, preferably to both faces of the felt, as shown in Figure 7 y In building a wall or partition, if without the use of'studding, the sheets are extended from top to bottomof the space to be enclosed and the upper and lower ends of the and will form a portions as shown in shown in Figure 9.

sheets are secured to horizontal cured to the ceiling and flooring of the room, as shownin Figure 1. With such an arrangement the sheets will preferably be supplied with asphalt on both surfaces so that the plaster can be applied to 'both surfaces of the felt. The plaster will firmly adhere to the asphalt andto the felt sheetsubstantial and satisfactory partition without the use of studding or lath, the vertical sheetswith the asphalt on each surface and the plaster applied ,directly to' the asphalt forming'm itself a'substantial partition or wall. I

We ordinarilyemploy what is known, as dry felt, which is a cellular material comosed of a mixture of vegetable and wool hber made by grinding up paper, rags and similar materia It is not essential to have the flanges 7 on the edges of the sheets as the meeting edges of the sheets may be overlapped and stapl es or nails driven through the overlapping Figure 8, or one flanged edge and one butt edge may be inserted as While this will leave a ridge in the surface, such ridge will .be

completely covered by the plaster which will in itself form a smooth surface firmly secured b the asphalt'coating to the felt sheet. We 0 not confine ourselves to any particavss I to form a flange at. Figure 1, and then strips 9 seular size or number of sheets to be used, as

and with a layer of asphalt upon the face of one of the sheets forming a plaster holding surface.

3. Plaster holding material comprising in combination a plurality of sheets of flexible material, said sheets being arranged in overlapping relation, each sheet projecting beyond the edge of the contiguous sheet and said sheets being united by a, layer of asphalt and a layer of asphalt upon the outer faces of said sheets forming plaster holding surfaces.

,4. A plaster wall comprising in combination a sheet of cellular material with a layer of asphalt upon the face thereof, and plaster applied to the outersurface of the asphalt.

5. Plaster holding material comprising in combination a sheet of unsaturated felt with a layer of asphalt upon forming a plaster holding surface.

6. A heat and sound insulating material the face thereof 7 sheets of dry felt, said sheets being united by a layer of asphalt and with asphalt ,upon the faces of the sheets. r

7. Heat and sound comprising saturated felt with a layer of asphalt upon the face thereof forming a surface adapted to receive plasten,

In witness whereof, we have hereunto set our hands this 14th day of June, "1927.v
